CORPORATION 01 NEW JERSEY WHEEL Application filed July 18, 1981. Serial No. 551,099.

The present invention relates to wheel constructions and includes novel constructions for wheels in car wheel truck assemblies and also locomotive drive wheels.

Among the objects of the present invention is to provide a novel wheel construction having arched ortions associated with the hub and rim of t e wheel, such portions being .-so designed that the same are in uniform compression, thereby eliminating localized stresses, such as occur at a junction of a spoke and rim of the present known wheel constructions. t

Another object of the invention is to provide a novel wheel construction in which arched portions under uniform compression are provided and which extend radially and outwardly from the wheel hub, each of these arched portions having a rim forming part for the wheel.

-The invention further contemplates the idea of roviding a novel wheel construction in whic the arched portions thereof and which radiate outwardly from the wheel hub are formed with a gradually tapering thickness of metal which enables the casting of such a wheel free from localized stresses existing in the present well known spoke design.

A Still further object of the invention is to provide a novel wheel construction in which the arched ortions thereof radiating outwardly from the wheel hub are channel shaped in cross-section and have a rim forming part, the wheel having rim forming parts between the channel shaped arched portions and integral therewith.

The invention further contemplates the idea of using the arched type of construction in a wheel construction having a separate tire forming portion-fitting the rim of the wheel, as well as in a wheel construction in which the rim and tire are formed integral, and whether or not either or both of these constructions are rovided with a crank-pin hub and counteralance.

A still further object of the present invention is to provide a novel locomotive drive wheel construction having a lead counterbalance pocket of such a esign that either.

a right or left wheel may be made from the same pattern by merel shifting the cores adjacent the pocket an the remaining portions of the wheel.

Still another object of the present invention is to provide a novel locomotive drive wheel construction having a lead counterbalance pocket, the remaining portion of the wheel having arched portions of the type hereinbefore set out extending outwardly from the hub of the wheel and a crank pin hub made integral with the wheel hub.

The invention still further contemplates theidea of providing a lead counter-balance pocket in a locomotive drive wheel construction, either with or without the arched construction heretofore referred to, havin or n.

radially I having a rim forming part. In the embodiment selected to illustrate the invention, spokes are provided intermediate the other spokes, these s okes being integral with the web and rimorming part thereof and extending inwardly and radially therefrom and terminating in spaced relation with the wheel hub.

With these and various other objects in view, the invention may consist of certain novel features of construction and operation as will be more fully described and particularly pointed out in the s cification, drawin i and claims appended ereto.

Figure 16 is a view in cross-section taken in a plane represented by line 16-16 of Figure 12 of the drawings and revolved through substantially ninety degrees.

Referring now more in detail to the drawings, an embodiment selected to illustrate the invention is disclosed in connection with a locomotive drive wheel or drive wheel cen-' ter 2, havin a wheel hub 4 and a crank-pin hub6forme inte al therewith. Extending outwardly from c wheel hub'4 and cran are etched portions 8,10, 12 and 14, each of them arched portions being oreedb vals'an integral therewith.

formed in the shape of a U, having a central web 16 and spaced side webs 18 and 20,.as clearly shown in Figure 5 of the drawings.

Each of these arched portions extends outwardly and circumfenentiallyand is provided with a-rim forming part or portion 22 of a shape similar to the cross-sectional view shown in Fi re 5 of the drawings. The side webs 18 an of the arched portions be-. tween the same are integrally connected to form rim forming parts or portions 24, these arts or portions being connected and rein g transverse ties 26 at s 'aoed inter- I etween the arched portions 10 and 12, the spoke forming webs 18 and 20th'ereof, are provided with a counterbalance 28 directly opposite the nected b run formin crank pin hub'6. 'In this embodiment, this I wheel or wheel center may be provided with atire having a flange tread portion adapted to fit therearound.

' In Figures 6 to 9 inclusive, of the drawings, the embodiment disclosed therein is of a similar construction, Figure 2, the same being provided with a wheel hub 30 having a crank pin hub 32 integral therewith and having arched portions 34, 36, 38 and 40 extendin outwardly therefrom, each of these arche portions having a rim forming part or portion 42 which is conside webs 44 similar to the we s 18 and 20 0 Figure 5 of the drawed together by-transverse ties 46 and the as, that disclosed in wheel or wheel center is adapted to have a tire 48: fitting therearound, this tire being provided with a flanged tread portion 50. The rim forming webs 44 intermediate the arched portions 36 and 38 are provided with a counterbalanee 52 oppositely disposed in relation to the crank pin hub 32.

In Figures 10 and 11, the present invention is shown embodied in a car wheel 54 having a wheel hub 56 and arched-portions 58, 60, 62

and 64 extending radially and outwardly therefrom and being provided with an integral rim and tire portion 66 provided with a flanged tread 68. The arched portions of this embodiment are of a similar construction in cross-section as that disclosedin Figure 5 of the drawings, the side flanges or webs 70.

thereof extending between t e arched portions and havingan integral rim and tire forming part or portion 72 provided with the flanged tread 68.

In each of the above embodiments, the archedportions having anintegral rim and/or rim and tire forming parts or portions are so designed that all parts of the arches are in uniform compression, thereby eliminatinglocalized stresses, such as occur at the junction between the spoke and rim of a wheel construction, as shown in Figure 1 of the drawings. Furthermore, the arches are l'oinedtojthe hubs of the wheel by a gradualy tapering thickness of metal, thus enabling the making of a casting free from localized stresses, such as those that haveheretofore existed in the present known wheels.

7 I'nF-igures 12 to 16 inclusive, the present novel wheel construction is shown in a locomotive drive wheel 74 having arched portions 76 and 78 of a similar construction the arched portionsof the previous embodlments, and a lead counterbalance pocket 80. The arched portions 76 and 78 extend-outwardl from a wheel hub 7 5.and a crank-pin hub 7 integral therewith, and are of a construction similar to the arched portions disclosed in the previously referred to embodiments. I

This wheel is further provided with the lead counterbalance This lead counterbalance'pocket is substantially opposite the crank-pin hub 77 and is provided with a transverse web 90 integral with the hub and with the spokes 82, 84, 86 and 88. This transverse web 90 has a rim forming part 92 and spokes 94, 96 and 98 integral therewith and intermediate the other spokes, which extend radially and inwardly from the rim forming part 92 and terminating in spaced relation with the hub 7 5, these intermediate spokes effectively reinforcing the web 90 and rim forming part 92. 7 As clearly shown in Figure 8 of the drawings, this particular embodiment of the invention may likewise be provided with a tire portion adapted to fit thereover and be secured thereto, to provide a finished locomotive drive wheel.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
